| 摘要 |
The preferred embodiments of the present invention provide a system and method for reducing the battery power required by a handheld device ( 300 ) that incorporates a graphical display ( 301 ). Graphical display ( 301 ), display drivers ( 307 ), LCD controller ( 403 ) and a memory ( 405 ) are optimized such that several pixels of information may be clocked simultaneously when the device is operating in a partial display mode. The optimized circuitry reduces the required refresh clock frequency ( 411 ) and thus the current drain on a device battery ( 319 ) thereby improving device operation time.
